polyelectrolyte polymers—types, forms, and function
the polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. the anionic polyacrylamide in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (phpa), although they are in actuality copolymers .

adsorption of different ionic types of polyacrylamide cost
specifically, it can be divided into non-ionic polyacrylamide (npam), anionic polyacrylamide (apam), and cationic polyacrylamide (cpam). c 3 h 7 on, c 3 h 6 o 2 , and c 5 h 9 o 2 n + are the basic structural units of these pam, resulting in different adsorption polarities [ 12 , 13 ].
degradation of polyacrylamide and its significance in nature,cationic pam easily adsorbs onto negatively charged clays, while anionic pam can bridge between clay surfaces via multivalent cations. 36 adsorption is enhanced by ion-dipole interactions between
the impact of high-quality polyacrylamide soil conditioner on soil
polyacrylamide is a water-soluble synthetic polyelectrolyte which consists of repeating units (forming a chain structure and containing hydrophilic groups). due to the different nature of the groups present in the macromolecules, polyacrylamide can be divided into nonionic, anionic, and cationic ones.

- What is modified polyacrylamide drilling fluid?
- Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.
- Can hydrophobically modified polyacrylamide gel be used in high temperature drilling?
- Enhanced hydrophobically modified polyacrylamide gel for lost circulation treatment in high temperature drilling J. Mol. Liq., 325 ( 2021), p. 115155, 10.1016/j.molliq.2020.115155 Rheological properties of bentonite-free water-based drilling fluids with novel polymer viscosifier J. Petrol. Sci.
- Can polyacrylamide be used for drilling?
- However, polyacrylamide with high molecular weight can be a good candidate at lower concentrations to meet the drilling requirements. The viscosity of polyacrylamide at all concentrations decreases with increasing temperature, according to Magzoub et al. (2021).
- What is the pH range of modified polyacrylamide drilling fluid?
- In addition, a modified grafted polyacrylamide was developed by using sodium hydroxide to maintain the pH value at 9. In conclusion, the modified polyacrylamide drilling fluid must be maintained in the pH range of 7 to 10 to avoid the formation of an acidic environment that is harmful to the environment and society.
